Users can enable VRRP on SVI interfaces (or Layer 3 VLANs) that have multi-chassis lag (MCLAG) ports as member ports. MCLAG allows links that are physically connected to two different Aruba 8400 devices to appear as a single lag port.

A router performs a Layer 3 route table lookup and Layer 3 forwarding when the destination MAC in the Ethernet frame matches its own MAC address (or virtual MAC address when the router is acting as a VRRP master). Otherwise the packets are switched.

In a topology with MCLAG and VRRP enabled, an MCLAG switch acting as a VRRP backup could receive IP packets with the virtual MAC address as the destination MAC. In this scenario, the MCLAG switch acting as a VRRP backup switches the traffic to peer (or VRRP master) using inter-switch-link and peer (VRRP master) performs the Layer 3 forwarding.
